DISCHARGE OUTLET FOR TANK CARS.

Application led September 9, 1921. Serial No. 499,504. f

To all whom t may concern.'

lie it known that I. JOHN J. Moliuuuc, rcsiding at Bayonne, HudsonCounty, State ot New Jersey, and being a citizen of the United States,have invented certain new and useful Improvements' in a Discharge Outletfor Tank Cars, of which the following is a full, clear, and exactdescription, such as Will enable others skilled in the art to which itappertains to make and to use the same, reference being had to theaccompany- `ing drawings, which illustrate the' preferred form of theinvention, though it is to be understood that the invention is notlimited to the exact details of construction shown and described, as itis obvious that various modiiieations thereof' Within the scope ot theclaims will occur to persons skilled inthe art.

In said drawings:

Fig. 1 is. a central vertical section of my improved discharge outletfor tank cars; and

Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1, the outletbeing shown in raised position in dotted lines.

It is the object of my invention'to provide an improved discharge outletfor tank cars of such construction that all parts ot the device may beprotected by the car sills when the device is not in use or the ear isin transit.

In the preferred embodiment of my device shown in the drawings, a tankof any desired construction having a tank sheet 1 is mounted upon asuitable car frame having the center sills 2 and 3. Secured to the tanksheet 1, as by rivets, not shown, is a discharge outlet comprising acasting 4, threaded internally at one end to receive a valve cage inwhich a valve sleeve 6 and discharge valve 7 are operated by means ot avalve rod 8 and hand wheel 9. At its other end, the casting 4 isprovided with an annular iiange 10 having a groove 11 in which is seateda packing washer 12 of any suitable material, as asbestos.

Rotatably mounted on the casting 4 is a casting 13 having an end adaptedto surround the end of `the casting 4 and engage with the packing washer12, the casting 13 beiner held in 'position on the casting 4 by the bolt14 which passes through openings in the castings 4 and 13 and isprovided with aspring washer 15 and nut 16. The adjustment ot nut 16 onbolt 14 is such that the cast-.ing 13 may be rotated on the casting 4and there will 'not be leakage past the washer 12. Openings 17 areprovided in the sills 2 and `3 for the insertion ot' the bolt 14 and thebolt 14 is held against rotation by having its head seated in an angularrecess in the casting 4. The other end of the cast-ing 13 is closed byan outlet cap 18 in the usuall manner.

When the outlet is in use, the casting 13 will be i-n the position shownin Fig. 1 and when the car is in transit the casting 13 will be intheposition shown in dotted lines in Fig. 2. that is, rotated on thecasting 4 until all` parts are above the lower edges ot' the centersills 2 and 3. The casting 13 is held in this position by a bolt 19which passes through openings 2O in the center/sills 2' and 3 and isheld in position by nut 21.

What I claim is:

1. -In a tank car, sills, a discharge outlet having a swiveled portionand means engaging said sills adapted to hold said swiveled portion inraised position.

2. In a tank ear, sills, a discharge outlet having a swiveled portionadapted to project below said sills and means adapted to hold saidswiveled portion in raisedposltion.

3. In a tank car, sills, a discharge outlet lhaving a swiveled portionadapted to project below said sills and means carried by said sillsadapted to hold said swiveled portion in raised positionbetween saidsills.

4. In a tank car, sills, a discharge outlet having a swiveled portionadapted to project below the sills and means adapted to hold saidswiveled portion above the lower edges of said sills.

5. In a tank car, sills, 'a discharge outlet mounted between said sillsand having a swiveled portion adapted to project below said sills andmeans carried by said sills adapted to hold said swiveled portion abovethe lower edges of said sills.

6. In a tank car, sills and a discharge outletmounted between said sillsand hav ing a swiveled portion adapted to be moved in a vertical planefrom a position inwhich it projects below the sills to a position inwich it lies above the lower edges of the s1 s.

7'. vIn a tank car, sills, a discharge outlet having a swiveled portionadapted to be moved in a vertica plane from a position in which itprojects below the. sills to a position in which it lies above the loweredges of the sills and means carried by the sills to l1old the swiveledportion in raised position. Y

8. In a tank car, sills, a discharge outlet `asing mounted betweensaidsills and comprising a rigid portion Yand a portion swiveled to saidrigid portion and a cap cara ried by sa-idr'swiveled,portion, saidcasing being adaptedto retain the leakageY 9. Inra tank car, sills, adischarge outlet casing mounted between said sills and comprising arigid portion lying :above the bottom edges of the sills and a portionswiveled to said rigid portion and adapted in one position to projectbelowsaid siis and in another position. to lie above the bottom edges ofthe sills.

10. In a tank car, sills, and a discharge outlet casing mounted betweensaid sills, said casino* comprising swiveled sections adapted to projectbelow said sills in one position and to lie above the bottom edges ofthe sills in another position and to retain leakage in both positions ofsaid casing.

ll. In a tank car, sills and a discharge outlet casing mounted betweensaid sills and comprising a rigid section and a movable section swiveledto said rigid section and adapted in one position to project below saidsills and in another position to lie above the bottom edges of saidsills, said casing being adapted to retain leakage in both positions ofsaid swiveled section.

12. In a tank car, sills, a tank carried by: said sills, a dischargeoutlet casing between said sills comprising a casing section iixed tosaid tank and a casing section pivoted on said fixed section so as tomaintain the pissagesin the two sections connected and means maintaininga fluid-tight joint between said casing sections.

13; In a tank car, sills, a tank carried by said sills and a dischargeoutlet casing for said'tank between Ysaid silis comprising a casingsection fixcdto said tank anda casing section pi'votally mounted on saidfixed casing section' and having a fluid-tight conection therewith.

14. In a tank car, sills, a tank carried by said sills and a .dischargeoutlet casing for said taiik between said sills comprising a. sectionixed to said tank and a section pivotally connected to the fixed sectionso as to provide a fluid-tight connection of the sections in allpositions of the pivotally connected section.

15. In a tank car, sills, a tank carried by said sills, a jointeddischarge outlet casing for said tank comprising a section fixed to saidtank and a section pivotaily mounted on said fixed section and a cap forsaid pivotally mounted section, the passages in said casing sectionshaving a luid-tight connection in all positions of the pivotally mountedsection.

In witness whereof my hand.
